Abstract: | Based on pot-culture experiments, the biological effect of rare-earth elements (REE) on antioxidation enzymes of wheat under
acid rain stress was studied. The results show that both acid rain and REE can affect the activity of anti-oxidation enzymes
of wheat to different extents. Under the acid rain stress, anti-oxidation enzymes (CAT, SOD) of wheat showed single peak curve
with the decrease of pH values. After REE were applled, variation of activities of anti-oxidation enzymes was relatively stable
and the peak value of variation curve would move in the direction of increased acidity. Under low acidity of acid rain, REE
could reduce the sensitivity of anti-oxidation enzymes of wheat to acid rain stress significantly and promote the resistance
of anti-oxidation enzymes of wheat to acid rain. |
